Dear All,

HST observed IR Com last night, all went well, and we got a
fantastic spectrum of this eclipsing SU UMa dwarf nova. As
always, your help was crucial to get this done!

BB Dor is next: Feb 13, 2013 20:57:03 to 23:53:50

It seems to be stuck at V~18.5, which is ~1mag above
the "true" low state,  but even then, it is terribly faint.
Please try to keep an eye on it for the next few days...
no risk of a sudden outburst, but we need to know
if it should decide to wake up.

While I'm here: two more targets are now locked on the
HST schedule,

SDSS1435+2336  Feb 15, 2013 22:05:53 to 02:16:17
HM-LEO               Feb 22, 2013 07:17:20 to 14:22:37

there is already some monitoring coming in, they look
both well-behaved so far.

Best wishes,
